PAIER-FEEDING MACHINE.

Application filed October 3, 1925. Serial No. 60,327.

My invention relaties to a paper feeding machine. Y

It is the object of my invention to provide a paper feeding machinehaving means to automatically buckle a top paper sheet by moving it in areverse direction to the direction of ejection, flutter the sheet andeject it, at the saine time automatically elevating additional sheets asdesired to maintain the sheets at a predeterminedpoint of elevation.

It is a further object to provide an ejecting mechanism as aself-contained air valve and also a controlling member in part for thebuckling mechanism, the ejector and the buckling mechanism beingoperated from the same shaft.

It is an object of myl invention to provide a single pump which may beused both to create the vacuum and the air pressure for fluttering' thesheets. It is my object to include inthe ejecting mechanisma reliefvalve for the ejector. It will thus make one self-*contained unit in theejector proper.

, Figure 6 is a detail view partially broken away and in section of thebuckling mecha- Figure 7 is an end elevation of the ratchet mechanismand means of connecting the ratchet mechanism to the automatic elevatingmechanism.

Referring to the drawings in detail, lis a base upon which is mounted adriving motor 2 which vdrives a pump 3 through a belt 4. This pump isprovided with awvacumn line on one side designated 5 and on the otheilside with a pair of pressurel lines 6 and 7. The exact details ofthispuinp are of no importancev provided Jthatl the usual vacuum canbecreated on one side and pressure on the other through the vexpulsionof air. f i I 'i The machinef'is Vcomposed of side frame ofthe kcompletemembers 8 which serve to support the mechaism hereinafter described.These side frame members are tied` together by transverse ross bolts 9and 10 which also serve as supports to the lugs 11 for the paper guides12 which determine the marginal position of the paper. The paper sheetsare stacked as at 13 on a platform 14 which is supported on either sideby jack screws 15 working in collars 16 in the platform. The lower endsof these screws are based in `the supporting collars 17 beneath which,attached to the screws, are. found the beveled gears 18 which mesh with`the beveled gears 19 on theoperating shaft 20. The size of the sheets tobe mounted on this platform is `to be determined by the maximum size ofthe machine and the maX- imum ksize of the platform. A single machinewill have a wide range o-f dimensions as indicated from the drawings inthis application. The rotation of the jack screws will serve ltolelevate the Y. stack of paper sheets. The supporting table 14 hasshoulders 21 oneither side which are yinserted through the guideways 22vony either side carried by the frame members to cooperate in. guidingthis platform up and down with its load of paper. f

The top of the paper sheets receives at the rear edge a nger23 which ismounted on a yshaft 24 through a collar'25 and set screw 26.y Anotherfinger of greater dimension in length designated 27 is also carried byvthis collar so that fingers of varying length vmay be used in connectionwith sheets of varying dimensions. The shaft 24 at its outside end iscarriedin a collar 28 which is fixed by a set screw 29 on a sliding rod30 carried in the bracket 31y on the upper side of thevmachine. This rodalso carries another collar 32 which in turn supports a rod 33 and a`weight 34. The position of the weight on the rod 33 may be. varied bythe setting of the set screw35. Suspended from this rod 30 is a lever 36attached by the collar 37 to the rod 30. The lower end of this leverl ispivoted yat 38 to alever 39; This lever 39 is pivoted at 40 on the sideofthe vframe of the machine. lts lower end carries-a spring finger 41which is adapted to pressvdown upon a pawl 42fwhich is weighted at oneend and is` pivoted in the middleat 43 on the lever 43a. `Thus When thelever 24'drops`down'due to the ejection `the engagement with theratchet. 43a is lpivoted to the link 45 which in turn, fat its otherend, is eccentrically mounted at 46 onthe driving wheel 47 which isdriven I' VVby the maindriving shaft 48 which receives of sheets and itis desired to elevate the platform to put the top sheets in ejectingposition, the rod 3()` is rotated on its axis and the levers 36 and 39are operated so that the spring 'finger 41 shifts 'from the rear itspower through lthe belt 49. This belt is finounted on the pulley wheel50 on the other .end ot the shaft 48.

Turning to the ejecting means proper, it

' will be lnoted that lthe vacuum line 5 leads toa distributor head V51which has a right- `angled aperture or passageway 52 therein.

This distributor .head is carried in one arm 5'3otaninverted 'IJ-shapedtra-me, the other arm of which is designated 54 Vand the head ot which55 is mounted by the set screws 56 ion the transverse.supporting rod57carried in .the side brackets 58 ot the ltrame.

This distributor .head is supported by a tubular shoulder'59 projectinginto the arm Nithin Ythis shoulder passing through a Yplate 60 Vis a setscrew V6l which engages with rtheend of the helical spring 62 in anaperture 63 within the distributor head. The screw `tits 'freely withinthis tubular member 59'so that thedistributor is springpressed lagainstthev ejector 64 in order that the-'ports l of .the `ejector 'mayVregister with the port of the distributor head. The vplate 60issupported by the set screw 65 which is threaded in the 'arm 53.

.The ejector Vdisc 64 'is lmounted on theV shaft 48 and turns therewith.This ejector disc has a plurality of ports 66 which are locatedfatan-angle to its major axis and are adapted to register with the port ofthe passageway 52 of the distributor head. These ports have vright handexit openings or ports Y 67 so that the; paper can be sucked up againstCII (Eil

the periphery of the ejector' disc when the ports 66 and 52 coincide. fY But in Vthe-illustration'shown in Figure 5 the construction is suchthat there is a side port 68 instead of the port 67 which is adapted toregister withv the port or passageway 69 in thebuclrling disc 70. Thisbuck-y ling disc has a central aperture 71 so that it Awill vlit uponthe stud shait 72. This stud 75 which is bolted to the buckling disc bythe 'screw 76. This gear 75 meshes with the gear 77 mounted by the setscrew 78 on the shaft 48. l

Returning to the ejector dis@ 64, a win be noted that it is providedwith a long, partially circular groove 79 which takes the place of anexhaust valve so that the pull upon `the Apump will not be so great thatthe je'ct through an opening 8O in a guide plate 8l against which thepaper is drawn on its underside `during the buckling and ej ectingoperations.

ln order that the sheets maybe fluttered the pipes 7 and 6, which arethe exhaust pipes from the pump, direct the exhaust air through nozzles82 which are placed at the angle-desired by means ot the collars 83 andset screws 84. These'collars are mounted on the'shaft 9.

Method 0f operation.

ln operation, when the pump is functioning, the air is evacuatedythrough the fdisftributor head 52 which, when the-parts are zintheposition shownin `Figure 5, serves to ldraw the sheet on top of thepile upwardly and move it'backwardly, as that is the direction ofmovement of the disc 70V against the stop lingeri23 :and stop `plate 85.As soon as the buclrling'has been effected the disc 70 has passed by thedisc 64 which is traveling inthe opposite direction so that thegports 69and 68 do not register butthe yports `68 andf52 registerwiththeport671in the preriphery ot' the ejector disc 64 which, dueto thevacuum in "the line, vpicks up the sheet and moves it in the reversedirectionout 'ot the iteeding machine into an adjacent machine'such as a`folder. lathe-meanwhile, the exhaust has been fluttering the' sheets tofacilitate Ytheir being picked up `by v`the buckler-.an'd ejector. Whenthe ejectionY is complete the exhaust groove 79 comes beneath the port52,. rendering the ejecti'ng mechanism inoperative'until a new sheet 1sengaged througha new cycle OTE-operations.V

The elevating mechanism has already been described,V so `that as soon.as'the sheets get downbelow apredetermined point, it will be broughtinto play and the sheets elevated again tothe point desired, at whichpoint the liitingof the rod`25 :by the elevated sheets willthrow theelevating Vmechanism out oioperation.`

Thus fthis machineV automatically elevates the sheets, gflutters them,buckles them by ,a reverse movement and ejects themout ot the machine,using the 'ejecting mechanism also as y.an exhaust valve lto. preventstalling of lsor the pump When the ejector is not ejecting the sheets.
